Doyle was a Maquis fighter who served on the raider the Val Jean under Chakotay until 2371.

In that year, the Val Jean and the USS Voyager were both stranded in the Delta Quadrant by the Caretaker's array. The Val Jean was destroyed by ramming a Kazon warship while fighting the Kazon-Ogla and as a result, the ship's crew, Doyle included, joined the crew of the USS Voyager as Starfleet personnel and traveled on the USS Voyager on its historic trek home from the Delta Quadrant. (VOY: "Caretaker")

He was assaulted by Tuvok while the Vulcan was under the control of Vedek Teero Anaydis on stardate 54167. (VOY: "Repression")

Doyle was played by Scott Alan Smith.
